Why Is Industrial Activated Carbon Widely Used?

Industrial Activated carbon widely used is becoming more and more widely known to people, but it also has its own characteristics during processing. How to make industrial Activated Carbon? What are the manufacturing processes of industrial activated carbon? In short, the production of industrial activated carbon good is divided into two steps: carbonization and activation. The preparation of industrial activated carbon first needs to carbonize the raw materials.

Carbonization, also known as pyrolysis, is to heat raw materials under the premise of isolating the air, and the general temperature is below 600 °C. Sometimes the raw materials are first dissolved by inorganic salts and then carbonized. After carbonization, industrial activated carbon raw materials will decompose and release gases such as water vapor, carbon monoxide, carbon dioxide and hydrogen; the raw materials will be broken down into fragments and recombined into a stable structure.

These fragments may be composed of some microcrystals. Microcrystals are formed by stacking two or more sheet-like structures with carbon atoms arranged in a hexagonal lattice. But there is no fixed crystal form for accumulation. The size of the microcrystal is related to the composition and structure of the raw material, and is affected by the carbonization temperature, which roughly increases with the increase of the carbonization temperature.
After carbonization, there are still some residual hydrocarbons attached to the boundary atoms of the microcrystals. The activation of semi-finished industrial activated carbon is to heat the carbonized material under the effect of an oxidizing agent to produce industrial activated carbon products. When the temperature of the oxidation process is 800-900°C, steam or carbon dioxide is generally used as the oxidant.
